To all whom t may concern,.- A`

Be it known that I, MARTIN B. MILLER, re-A siding at Omaha, in thecounty of Douglas and State of Nebraska, have invented certain usefulImprovements in Automatic Cream- Coolers; and I do hereby declare thatthe following is a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,which form aA part of this specification. g

This invention has relation to a new and novel improvement in automaticcreamcoolers.

The object of my inventionis to provide a tank adapted to contain creamand within which tank is to beheld a cooling-coil adapted to be carriedgently through the cream to cool the same; and my invention embodies thecombination of certain instrumentalities, as will be described more.fully hereinafter and finally pointed out in the claims. I

In the accompanying drawingsIhave shown in Figure 1 a side elevation ofan automatic cream-cooling tank embodying my invention.Y Fig. 2 shows atop view with portionsre moved. Fig. 3 showsa centralsectional view,while Fig. 4E shows a detached detail disclosing the arrangement of thecooling-coil and the connected float.

Myinventionembodies,essentially,awatertight trough supported by means ofthe legs 2 2 and embracing the ends 1 1, the sides-A,- and the bottom 3,as disclosed. Extending from this water-tight trou gh is al suitablestopcock 4, as is disclosed in Figs. 1 and 3, located near the bottom,while preferably at the same end and above the stop-cock is anescape-pipe 5. This trough is adapted to contain a cream-holdingreceptacle or tank B, preferably provided above with theoutwardly-flared edges c, by means of which this tank is heldfwithin thetrough'A. This tank is preferably flared inward, so that the bottom areais smaller thanthe upperend of the tank, as will be understood inreferring to Fig. 3. Extending from the bottom of this -tank B, adaptedto contain the cream, is a suitable stop-cock 10, so that this tank maybe drained.

Z. Serial No. 93,719. (No model.)

troughisa central cover 7, to which are secnredtih'e lids S, reinforcedby means of the grates, as is clearly shown'in- Fig. 3; L'Located uponthe central top portion G is a water-tank F, from which tank extendsupward apipe c, (shown in the top view in Fig. 2 and in a dottedelevation in Fig. 3,) this pipebeing in open communication with thewater-tank F, so' that the water rising within the tank will yalso risewithin this cohnected tube or pipe c. From a pointpreferablyopp'osit'e'the intake- `point of the tube or pipe c extendsa Siphon H,which siphon is also in open communication with this water-tank F, andthis siphon is direct-ed into the lower water-tank A, as is disclosed inFig. l, where the dotted end of the siphon His disclosed. Accordinglywhen the water riseswithin this upper tank and findsan escapementthrough the siphon II the siphon will be primed and so empty'this 4upperwater-tank F. This tank'Fis preferably roundth`o'ugh'it may be of anysuitable conformation, and held therein is a suitable Iioat C of apredetermined lifting capacity, from 'which project upward and thencedownward l.the supporting-brackets b, so positioned that l,they extendupward over the edge cf the watertank F and downward through suitableopenings within the coverings 6 and 8 almost to the bottom of thecream-holding tank or receptacle B, as is clearly shown in Fig. 3. Belowthese brackets b are secured to the bars 12 l2, which in turn aresecured to the cooling-coil D, comprising a plurality of connected tubesof a length almost the length of the cream'- holding receptacle andbeing coiled from end to end, as is shown in Fig. 2. The capacity of thefloat C, which may be a copper tank or be composed of any other suitablematerial, is in excess of the work of the cooling-coil D and thebracketsv b. Oneend of this cooling-coil D is extendednpward to providethe termination 13, as is shown'vmore clearly in Fig. 4, while theremaining-tend terminates in the gooseneck 14', which gooseneck isadapted to work withinthetube c, as is shown in top view in Fig. 2 andindotted lines in Fig. 3. is positioned a suitable wa ter-supply tank18, from which extends an elastic tubing l7-as an Extending transverselyacross the top of the ordinary garden-hose', for instance-the end4.Adjacent this water-tank F ICO of which is secured to the upward coilextension 13, which passes through a suitable opening within the top 6,as does also the gooseneck 1-l.

Now in the use of my cream-cooler the operation would be as follows: Thecream to be cooled would be placed within the cream tank or receptacle.The cooling-water from the tank 1S would next be permitted to llow rosein this tank it would rise within the Siphon I-I, as well as raise thefloat C and the conn ccted cooling-coil D, secured to the same by thebrackets b. In gently rising through the cream the cream would be gentlyagitated and cooled by the flowing water passing through the same, andthis coil would rise upward a suitable height, determined by theoverflow of the water through the siphon II. As soon as the siphon IIwas started the water would Iiow out of the tank F, the siphon beingmade of a larger capacity than the intake water supply entering the tankF through the gooseneck 1st, the instru mentalities being so arrangedthat the coil D would descend at about thesame rate of speed that itrose until the water-tank F was emptied. During the period of thesiphoning it is of course understood the water-supply is continuallyentering this tank F through the pipe 17 and the coil, as has beendescribed. Now as the tank F gradually Iilled up again the coil would becarried upward, so that this cooling-coil D is continually operatedupward and downward to be carried through the cream to cool the same.However, the water which was first made to circulate through the coil Dto cool the cream and thence raise the coil would be still used, in thatit would next ll the space between the trough and the cream-tank B,rising between the same until it found an outlet through the pipe 5.From this it will be n0- ticed that the stream is used twice to cool thecream and, in addition, made to operate the instrnmentalities to raiseand lower the coil. Vhile I have described the water as being drawn fromthe tank 1S, it is of course linderstood that the tube 17 would be inconnection with some suitable water-supply-as a city service, forinstance. Now after the cream has been suiiicientlycooled the operatorwould open the stop-cock 10 and draw oit the contents, so that the tankwould be given a thorough cleansing. The coilD being buta simple tube itcan be easily cleaned, and so, also, it should be remembered that thetube 17 be placed in connection with a warm or hot water supply, sothat, if desired, the cream or other batch within the receptacle or tankB could be raised in temperature, if that were desired.

The device is neat and simple of construction, and the working effectsare so arranged that they may be easily cleansed, and

Having thus described my said invention, what I claim as new, and desireto secure by United States Letters Patent, is-

1. The combination with a suitable trough having an outlet, of a tankheld within said trough, a water-receptacle above saidtank, a Siphonextending from said receptacle and emptying into said trough, a floatwithin said water-receptacle, a cooling-coil secured to said float, oneend of said cooling-coil being in connection with a suitable intake, theremaining end connected to said water-receptacle.

2. The combination with a trough, of atank held within said trough, anexit-pipe extending from said trough, a drain-cock secured to said tank,a water-receptacle secured above said tank, a siphon extending from saidwater-receptacle and entering said trough, a cooling-coil within saidtank both ends eX- tending upward, one terminating in a gooseneckconnected to said water-receptacle, the remaining end being inconnection with the Water-supply, and a float within saidwaterreceptacle secured by means of brackets to said cooling-coil, allarranged substantially as and for the purpose set forth.
